In the latter examples, the code will be executed at least once. If there is another line inwards, it marks the transition to a filled area. Basic Programming Examples Creating a Dialog Handler Creating Event Listeners Getting Session Information Identifying the operating system Monitoring Document Events Opening a Dialog With Basic Programming Examples for Controls in the Dialog Editor Calling Python Scripts from Basic Related Topics LibreOffice Basic Help Please support us! Until Basic encounters the End With statement, it looks for partly-qualified names: names that begin with a period (unary dot-operator). A problem may arise if you click on No: the styles will not be updated, and the automatic-update feature will be turned off. For example, headers or footers are added to the page style. The Step property of a dialog defines the current tab page of the dialog whereas the Step property for a control element specifies the tab page where the control element is to be displayed. In other words, the methods are assigned (as combinations) to the service in interfaces. The query object is first created using the createUnoService call, then initialized, and then inserted into the QueryDefinitions object by means of insertByName. The. The definition will then be available to all routines in the module. LibreOffice Basic offers complete access to all LibreOffice functions, supports all functions, modifies document types, and provides options for creating personal dialog windows. ThisComponent returns the currently active document. In particular, if such a request is made by pressing the right mouse button on the control, the event will be fired twice: once for the popup menu request, and once for the real mouse event. The example creates a TextTables list containing all tables of a text that are traversed in a loop. The second parameter specifies the text that is to be saved as a line of the text file. If this is not the case, it must be determined using the preceding code. Whereas in VBA the paragraphs are accessed by their number (for example, by the Paragraph(1) call), in LibreOffice Basic, the Enumeration object described previously should be used. Multiple modules can be combined to a library. In many instances, it is the case that a text is to be searched for a particular term and the corresponding point needs to be edited. The regular expressions supported by LibreOffice are described in detail in the online help section for LibreOffice. (For Writer documents only, you can use the Template Changer extension to set this feature again.). com.sun.star.chart.ChartTitle contains not only the listed formatting properties, but also two other properties: The legend (com.sun.star.chart.ChartLegend) contains the following additional property: The following example creates a chart with a title "Main Title String", a subtitle "Subtitle String" and a legend. Purchase or download the latest LibreOffice Calc Guide, written by community experts. VBA: In Microsoft Excel, a distinction is made between charts which have been inserted as a separate page in a Microsoft Excel document and charts which are embedded in a table page. The simplest variant is a single-color fill. The service recognizes the following properties: If these settings are changed, then all of the pages in the document are affected. First it splits "Source" dividing it at all "Search", and joins the parts back with "NewPart". The expression MB_YESNOCANCEL + MB_DEFBUTTON3 is harder to write, but easier to understand. To access the view of a control element form, you need the associated model. VBA: Whereas the structure of an object in VBA is defined by the class to which it belongs, in LibreOffice Basic the structure is defined through the services which it supports. LibreOffice BASIC Programming Guide. Global variables are declared in the header section of a module using the keyword Global: Private variables are only available in the module in which they are defined. Below, you will find a list of the most important properties for control element forms. The interface com.sun.star.sheet.Spreadsheets provides a better method to create a new sheet: insertNewByName. The following control codes are available in LibreOffice: To insert the control codes, you need not only the cursor but also the associated text document objects. Bookmarks are created and inserted using the concept already described previously: The example creates a Cursor, which marks the insert position of the bookmark and then the actual bookmark object (Bookmark). Instead of producing an error message, the interpreter initializes the typing error as a new variable with a value of 0. The forms created in this way provide all the functions of a full database front end without requiring independent programming work. This chapter provides an overview of the key elements and constructs of the LibreOffice Basic language, as well as the framework in which applications and libraries are oriented to LibreOffice Basic. The following values are available: The following example creates a circular slice with a 70 degree angle (produced from difference between start angle of 20 degrees and end angle of 90 degrees). The following expressions assign the various Unicode values to the code variable: ensures that the MyString string is initialized with the value of the number 13, which stands for a hard line break. Finally the code sets the Label property of the control element to the New Label value. Base includes additional functionality that allows you to create full data-driven applications. Special cell formatting is handled by the com.sun.star.table.CellProperties service. You can also use plus (+) or minus (-) signs as prefixes for decimal numbers (again with or without spaces). com.sun.star.awt.UnoControlTimeField, A numeric field makes it possible to enter, display and edit formatted numeric values. The effect on any particular function is described with that function, below. The Replace function used for replacing does not fall within the standard linguistic scope of LibreOffice Basic. RectangleShape.String = "This is a test" If another error occurs, the system outputs a warning. It marks a certain point within a text document and can be navigated in various directions through the use of commands. If a decimal number is assigned to an integer variable, LibreOffice Basic rounds the figure up or down. The database interface from LibreOffice is available in the LibreOffice Writer and LibreOffice Calc applications, as well as in the database forms. The view of the control element can then be determined with the assistance of the model and using the document controller. In addition to the FillTransparence property, the com.sun.star.drawing.FillProperties service also provides the FillTransparenceGradient property. All drawing objects that can have a border line support the com.sun.star.drawing.LineStyle service. Before the corresponding call can be made, the polygon must be inserted into the document. This ensures that at any one time, only one option button is set. All formatting options for individual characters and paragraphs are therefore automatically available. libreoffice basic programming guide pdf By July 27, 2021 OpenOffice Basic . This help section explains the most common functions of LibreOffice Basic. If you move a database table into a spreadsheet, LibreOffice creates a table area which can be updated at the click of the mouse if the original data has been modified. The interfaces to various LibreOffice applications, which allow for direct access to Office documents. The following example creates a rectangle shape and fills it with red (RGB value 255, 0, 0): If you set the FillStyle property to GRADIENT, you can apply a color gradient to any fill area of a LibreOffice document. In place of the $ placeholder, the Format function displays the relevant currency symbol defined by the system (this example assumes a European locale has been defined): The format instructions used in VBA for formatting date and time details can also be used: LibreOffice Basic provides the Date data type, which saves the date and time details in binary format. The same applies when attempting to assign a string to a Boolean variable: Again, the basic interpreter reports an error. If the cursor of LibreOffice is in a cell, then the name of that cell can be seen in the status bar. If the center of a paragraph, for example, contains a word printed in bold, then it will be represented in LibreOffice by three paragraph portions: the portion before the bold type, then the word in bold, and finally the portion after the bold type, which is again depicted as normal. The document object of a spreadsheet is based on the com.sun.star.sheet.SpreadsheetDocument service. At the end, the drawing object is assigned to a page using a Page.add call. You can also edit documents or open databases with event handling as well as access other control elements. The preceding Filename and Title properties are of the string type. The control elements of dialogs and forms differ in several aspects. A single key action on a modification key, such as the Shift key or the Alt key does not create an independent event. LibreOffice Basic provides the MsgBox and InputBox functions for basic user communication. The found expressions differ by up to two letters from the search expression: Note: English documentation | LibreOffice Documentation - LibreOffice User Guides en / English documentation English documentation Getting Started Books Buy a printed copy Download PDF Guide Source Files Website Buy a printed copy Download PDF Download Source Files Read in your browser Buy a printed copy Download PDF Download Source Files The FileProperties array has two elements, one for each option used. Here are a few correct and incorrect examples of numbers in exponential format: Note, that in the first and third incorrect examples that no error message is generated even though the variables return incorrect values. Page properties are the formatting options that position document content on a page as well as visual elements that are repeated page after page. No programming knowledge is needed to use the corresponding functions. In the previous example, if the UserInput variable contains a valid numerical value, then this is assigned to the ValidInput variable. The Format function formats numbers as a string. For more in-depth information please refer to the OpenOffice.org BASIC Programming Guide on the Wiki. They can be displayed as 2D or 3D graphics (com.sun.star.chart.Dim3Ddiagram service). This allows numbers to be handled in a manner which more closely reflects machine architecture. The Environ function returns the environmental variables of the operating system. Some drivers access file-based databases and take the data directly from them. Each time the function is called, the values generated previously are not available. Note: If you want to keep the original values, use the Preserve command: When you use Preserve, ensure that the number of dimensions and the type of variables remain the same. This includes the distance of the paragraph from the edge of the page as well as line spacing. If you use the CompatibilityMode ( true ) function, LibreOffice Basic will behave like VBA. Date literals allow to specify unambiguous date variables that are independent from the current language. VBA: The rules for constructing markers are different in LibreOffice Basic than in VBA. Another mechanism for changing the text of headers and footers is available for text documents (LibreOffice Writer) because these consist of a single block of text. From a Set of ASCII Characters to Unicode, Dynamic Changes in the Dimensions of Data Fields, Determining the Dimensions of Data Fields, Array Creation, value assignment and access example, Programming Example: Sorting With Embedded Loops, Terminating Procedures and Functions Prematurely, Specification of Date and Time Details within the Program Code, Copying, Renaming, Deleting and Checking the Existence of Files, com.sun.star.lang.XMultiServiceFactory Interface, com.sun.star.container.XNameAccess Interface, com.sun.star.container.XNameContainer Interface, Index-Based Access to Subordinate Objects, com.sun.star.container.XIndexAccess Interface, com.sun.star.container.XIndexContainer Interface, com.sun.star.container.XEnumeration and XenumerationAccess Interfaces, Basic Information about Documents in LibreOffice, Creating, Opening and Importing Documents, Replacing the Content of the Document Window, Default values for character and paragraph properties, Example: searching and replacing text with regular expressions, Inserting, Deleting, Copying and Moving Cells, Definition of Elements to be Printed (Spreadsheets Only), Type-Specific Methods for Retrieving Values, Closing With the Close Button in the Title Bar, Working With the Model of Dialogs and Control Elements, The Three Aspects of a Control Element Form, Accessing the Model of Control Element Forms, Accessing the View of Control Element Forms, Accessing the Shape Object of Control Element Forms, Determining the Size and Position of Control Elements, #Scope_of_Variables Scope and Life Span of Variables, '''#Default values for character and paragraph properties''', https://wiki.documentfoundation.org/index.php?title=Documentation/BASIC_Guide&oldid=592397, Creative Commons Attribution-ShareAlike 3.0 Unported License, Addition of numbers and date values, concatenation of strings, Division of numbers with a whole number result (rounded), modulo operation (calculation of the remainder of a division), Implication (if the first expression is true, then the second must also be true), Equality of numbers, date values and strings, Inequality of numbers, date values and strings, Greater than check for numbers, date values and strings, Greater than or equal to check for numbers, date values and strings, Less than check for numbers, date values and strings, Less than or equal to check for numbers, date values and strings. In these situations, the XEnumeration and XenumerationAccess interfaces are appropriate. Whereas an ODBC data source only covers information about the origin of the data, a data source in LibreOffice also includes a range of information about how the data is displayed within the database windows of LibreOffice. Therefore, before copying the content from B to A, B has to be converted into A's internal format. By means of a storeAsURL method option, the user can save the original XML files directly. LibreOffice Basic also offers several other services through which you can modify such properties, as formatting or apply fills. The functions responsible are insertByName, removeByName and replaceByName. The TextCursor object in LibreOffice Basic acts independently from the visible cursor in a text document. The code used in the example then creates a list containing all charts of the first spreadsheet (Charts line = Doc.Sheets(0).Charts). Charts are not treated as independent documents in LibreOffice, but as objects that are embedded in an existing document. The following is a practical example of this. The example first creates a list containing all rows using a Table.getRows call. The following call creates a copy of the Source file under the name of Destination: With the help of the following function you can rename the OldName file with NewName. In Example 1, the page is accessed by its number (counting begins at 0). This guide provides an introduction to programming with LibreOffice Basic. The structure is further complicated by tables. When specifying a service name, it is only the module name which is of any importance because this must be also listed in the name. Rectangle shape objects (com.sun.star.drawing.RectangleShape) support the following services for formatting objects: The Service com.sun.star.drawing.EllipseShape service is responsible for circles and ellipses and supports the following services: In addition to these services, circles and ellipses also provide these properties: The CircleKind property determines if an object is a complete circle, a circular slice, or a section of a circle. You can add custom dialog windows and forms to LibreOffice documents. Note: The color intensity of the start and end colors is 150 percent (StartIntensity and EndIntensity) which results in the colors seeming brighter than the values specified in the StartColor and EndColor properties. They provide the framework for dividing a complex problem into various sub-tasks. It only allows iteration to be applied forward, and for values to be interrogated. The InteractionHandler ensures that LibreOffice asks the user for the required login data. As the number of these words is initially unknown, you need to be able to subsequently change the field limits. The Resume Next command continues the program from the line that follows where the error occurred in the program after the code in the error handler has been executed: Use the Resume Proceed command to specify a jump point for continuing the program after error handling: The term Proceed is a label. The True value of the IsDate property results in only the date and not time being displayed. The, a Boolean variable which specifies whether the, com.sun.star.text.textfield.CharacterCount. VBA: LibreOffice Basic does not support the VBA Like comparison operator. A complete list of all text fields is provided in the API reference in the com.sun.star.text.textfield module. The Map AppFont (ma) replaces the Twips unit to achieve better platform independence. You can assign a date to a date variable through the assignment of a simple string: This assignment can function properly because LibreOffice Basic automatically converts the date value defined as a string into a date variable.
